Brillouin microscopy for ocular biomechanics
Conference on Lasers and Electro-Optics 2010, 2010We present Brillouin confocal microscopy with high throughput and high extinction for non-invasive mechanical measurements of tissue and biomaterials. In particular, we demonstrate biomechanical characterization of crystalline lens and cornea.

Coaxial line scanning Brillouin microscopy
Optical Elastography and Tissue Biomechanics XIIAbstractConfocal Brillouin microscopy (CBM) enables high-resolution mechanical imaging but has slow acquisition speeds due to its point-by-point scanning strategy. Line-scanning Brillouin microscopy (LSBM) offers imaging acquisition speed improvements but faces challenges such as beam distortion in biaxial configurations and insufficient extinction ...

Brillouin Scanning Microscopy in Keratoconus
2016The mechanical properties of the cornea are thought to be central in the development of keratoconus and other corneal ectatic disorders. However, current technologies to measure mechanical properties are limited for in vivo and/or in situ applications. We have recently introduced a new approach, based on optical Brillouin scattering, toward developing ...

Microwave induced phonons imaging by Brillouin microscopy
IEEE Ultrasonics Symposium, 2005., 2006Bulk Acoustic Waves (BAW) as well as Surface Acoustic Waves (SAW) have been studied by Brillouin Spectroscopy (BS). Experiments performed on Lithium Niobate single crystals and Zinc Oxide thin films have pointed out that BS is able to detect piezoelectrically induced phonons.

Brillouin microscopy: exploring niche applications (Conference Presentation)
Optical Elastography and Tissue Biomechanics VI, 2019Brillouin microscopy is an emerging tool of biomedical imaging [1]. While for a long time Brillouin spectroscopy was considered an exquisite tool of precise spectroscopy, recent advancements in instrumentation, methods of signal and data analysis, and multimodal imaging have paved the way to new applications in the broad area of biomedical research.

Brillouin microscopy for tissue and cell biomechanics
CLEO: 2015, 2015We have developed an all-optical approach to measure material mechanical properties using Brillouin light scattering. Brillouin imaging uses the elastic modulus as contrast mechanism. We demonstrate its application in vivo for tissue and cellular biomechanics.
